5. Long lifespan, recharging for over 500 times

Cell phone no electricity to take two steps:

A new device may allow you to take energy out of natural motion and use it to charge your smartphone. Developed by researchers at the Massachusetts Institute of Technology, the system uses mechanical energy to generate voltage and generate electricity only with a little bending. Its size and inherent flexibility may be applied in wearable smart devices and other electronic products in the future.

According to MIT News, the researchers said the system is capable of cheap, mass production. The electrochemical technology used in this bendable device has a similar working principle as a cell or fuel cell.

Researchers sandwiched liquid-electrolyte-laden polymers between lithium alloys as electrode materials. When lithium alloys are stressed and bent, lithium ions will cross the polymer and create voltages and currents that can be used in electrical equipment.

If you put a little weight on one side of the device, it will bend as people walk and other daily activities. So far, the efficiency of the first generation model is as high as 15%. However, researchers say the process of converting mechanical energy to electrical energy will be when the device is in optimal working condition.

In an interview, Professor M Li from MIT said that the device is not limited by the second law of thermodynamics, so in principle it can achieve efficiencies of up to 100%
